HEY CHECK THIS OUT!!!!

I switched in my geforce3 ti200 into my SOYO P4X400 MB.

$dmesg
nvidia: loading NVIDIA Linux x86 NVdriver Kernel Module 1.0-3123 Tue Aug 27 15:56:48 PDT 2002
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: Detected Via Apollo Pro P4X400 chipset
agpgart: AGP aperture is 64M @ 0xd0000000
NVRM: AGPGART: VIA Apollo KT133 chipset
NVRM: AGPGART: aperture: 64M @ 0xd0000000
NVRM: AGPGART: aperture mapped from 0xd0000000 to 0xe1ab5000
NVRM: AGPGART: mode 4x
NVRM: AGPGART: allocated 16 pages

From my prior dmesg with the GF4 in I can see: NVRM:AGPGART: aperture: 64M @ 0xe0000000

I don't know, but the memory allocation was different, Course it is a different card but same Northbridge.

[user@redbox agp]$ cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: AGPGART
AGP Rate: 4x
Fast Writes: Disabled
SBA: Disabled

[user@redbox agp]$ glxgears
16194 frames in 5.0 seconds = 3238.800 FPS
18146 frames in 5.0 seconds = 3629.200 FPS
18111 frames in 5.0 seconds = 3622.200 FPS


I thought these were unified drivers????
MY GEFORCE4 ti4200 does not work with via's P4X400 chipset, but my Geforce3 ti200 does???

Now I know the Geforce4 is ok. It worked great with my ABIT KG7-Raid MB, which also has a VIA chipset on it. The difference? My GF4 has to us the agpgart AGP module on the P4X400 chipset MB, but it was using NvAGP on the Via 133 (abit KG7-raid MB).

So GF4 on the P4X400 series mb (SOYO P4X400 Dragon ultra) = BAD (why I am uncertain, because my GF3 is forced to use agpgart on this MB also).

GF3 on on the SOYO = Good. still using agpgart.

GF4 on KT133 (abit kg7-raid) using NvAgp) = good.

I wonder if using agpgart w/ the GF4 on the KT133 chipset will result in lockups. Bet it does. Will know real soon.

Also to note. I mentioned I had been using windows (this is being done from RH8 btw )...

Well I decide to try some things. EVERY TIME I STARTED AN OPENGL SCREEN SAVER IT LOCKED UP WINDOWS ALSO!!!!!!!!!!!!!!!!!!!!!!!!!!

DEFINITE PROBLEM. w/ GF4 and the P4X400 chipset!!!

I am bald now after a week, but am releived.

Nvidia. You gotta do something about this!!!! Please!!!!! This same info is going to VIA tech. as I have been asking them for help also.
